Adversaries may stop or disable services on a system to render those services unavailable to legitimate users. Stopping critical services or processes can inhibit or stop response to an incident or aid in the adversary's overall objectives to cause damage to the environment.(Citation: Talos Olympic Destroyer 2018)(Citation: Novetta Blockbuster) Adversaries may accomplish this by disabling individual services of high importance to an organization, such as <code>MSExchangeIS</code>, which will make Exchange content inaccessible.(Citation: Novetta Blockbuster) In some cases, adversaries may stop or disable many or all services to render systems unusable.(Citation: Talos Olympic Destroyer 2018) Services or processes may not allow for modification of their data stores while running. Adversaries may stop services or processes in order to conduct [Data Destruction](https://attack.mitre.org/techniques/T1485) or [Data Encrypted for Impact](https://attack.mitre.org/techniques/T1486) on the data stores of services like Exchange and SQL Server, or on virtual machines hosted on ESXi infrastructure.(Citation: SecureWorks WannaCry Analysis)(Citation: Crowdstrike Hypervisor Jackpotting Pt 2 2021) Threat actors may also disable or stop service in cloud environments. For example, by leveraging the `DisableAPIServiceAccess` API in AWS, a threat actor may prevent the service from creating service-linked roles on new accounts in the AWS Organization.(Citation: Datadog Security Labs Cloud Persistence 2025)(Citation: AWS DisableAWSServiceAccess)

CVE	Description	Severity	EPSS	Modified
CVE-2019-1747	A vulnerability in the implementation of the Short Message Service (SMS) handling functionality of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to trigger a denial of service (DoS) condition on an affected device. The vulnerability is due to improper processing of SMS protocol data units (PDUs) that are encoded with a special character set. An attacker could exploit this vulnerability by sending a malicious SMS message to an affected device. A successful exploit could allow the attacker to cause the wireless WAN (WWAN) cellular interface module on an affected device to crash, resulting in a DoS condition that would require manual intervention to restore normal operating conditions.	HIGH8.6	2.39%p82	2024-11-21
CVE-2019-3728	RSA BSAFE Crypto-C Micro Edition versions from 4.0.0.0 before 4.0.5.4 and from 4.1.0 before 4.1.4, RSA BSAFE Micro Edition Suite versions from 4.0.0 before 4.0.13 and from 4.1.0 before 4.4 and RSA Crypto-C versions from 6.0.0 through 6.4.* are vulnerable to an out-of-bounds read vulnerability when processing DSA signature. A malicious remote user could potentially exploit this vulnerability to cause a crash in the library of the affected system.	HIGH7.5	2.39%p82	2025-11-04
CVE-2019-1711	A vulnerability in the Event Management Service daemon (emsd) of Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper handling of gRPC requests. An attacker could exploit this vulnerability by repeatedly sending unauthenticated gRPC requests to the affected device. A successful exploit could cause the emsd process to crash, resulting in a DoS condition. Resolved in Cisco IOS XR 6.5.1 and later.	NONE	2.30%p81	2024-11-21
CVE-2019-1886	A vulnerability in the HTTPS decryption feature of Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to insufficient validation of Secure Sockets Layer (SSL) server certificates. An attacker could exploit this vulnerability by installing a malformed certificate in a web server and sending a request to it through the Cisco WSA. A successful exploit could allow the attacker to cause an unexpected restart of the proxy process on an affected device.	HIGH8.6	1.35%p68	2024-11-21
CVE-2020-3134	A vulnerability in the zip decompression engine of Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper validation of zip files. An attacker could exploit this vulnerability by sending an email message with a crafted zip-compressed attachment. A successful exploit could trigger a restart of the content-scanning process, causing a temporary DoS condition. This vulnerability affects Cisco AsyncOS Software for Cisco ESA releases earlier than 13.0.	MEDIUM6.5	1.09%p61	2024-11-21
